As you zoom in from the nationwide county-level map, census tracts display at about 200
miles, block groups at 50 miles, and streets at 5 miles.

Additional maps include 2000 census data on ethnicity, education, and poverty. Change maps by clicking the
drop-down menu under "Compare Maps" on the left.

The SocioEcon Mapper has been online since 2002.
Until the launch of
PolicyMap in
May 2008, FairData
was the only free publicly available source for nationwide block group-levelinteractive maps
showing socioeconomic characteristics. We encourage all users
of the SocioEcon Mapper to check out PolicyMap.

This map shows block group level median income in 1999 for Delaware, DC, Maryland, and Virginia. It is derived from Map 1 of the SocioEcon
Mapper. (Thanks to UCL's Google Map Creator)

You can search the map by address in the form above the map. Query for info from the 2000 census by clicking the balloon markers. If
you need absolute precision along boundaries, you should use the SocioEcon Mapper, as there are locational discrepancies between the Census Bureau block group geography and streets
as displayed on the Google map.

New 6/06:Added
a Find menu item to the Google base map (also available via the FairData pop-up FIND form -- refresh search form window if not displayed).This is an alternative
way to search for addresses, with clickable links back to the FairData map.Click here to view the map and
form.. See GMap Help for additional details.

In 2006 we added a link to newly released DataPlace for more
detailed "build your own" analysis -- (no block groups, tract-level and higher). Select the field DataPlace_Link from the INFO tool pop-up window for a census
tract in the FairData map and you'll see that tract in a new DataPlace area overview window, with links
to thematic maps, and exceptional charts and tables across a wide range of datasets. (Click on the links under
"Browse by Topic" in the right corner beneath the DataPlace map to quickly change the theme to another
indicator.)

Social Explorer is another excellent source for tract-level and higher maps and tables from the 1990 and 2000 census. (In many instances, the maps are superior to DataPlace
maps because more meaningful thematic breakpoints are used.)

On the FairData map, tract lines generally display as faint white lines overlaying the component block group boundaries
when you check the box "Census Tract High", then select Redraw. To zoom to the block group level components of a tract you have identified in the DataPlace map: (1) copy the
tract number (for example,51550-0201 displayed via the question mark button on the
DataPlace map ) into the block group search field on the popup form accessed with FairData's FIND button (2) remove the hyphen (and the decimal point, if there is one) and
click "Find". A table with data for the component block groups will display below the map.

Maps 11 and 12 are color-coded at the block group level only. Color coding is not applied to the county or tract levels (75-200-mile scale), since the
absolute numbers depicted by the dots are more meaningful . The dots are scattered randomly by tract or county, and do not represent specific population centers..

ZOOM IN or use the FIND button for block group level analysis (i.e. a scale of about 0 to 50 miles)

At the tract level, scaled blue dots represent persons (50 and higher) with limited English-speaking ability; and at the county level scaled red dots
represent persons (100 and higher) with limited English speaking ability. At a scale of about 10 miles, the actual block-group level numbers are displayed in purple
boxes.

Color coding shows the percentage of Spanish speakers who either "do not speak English well" or "do not speak English at all". At a scale of about 10
miles, block group population counts for these two limited English categories are displayed in purple boxes.

Note: Some official definitions (for instance, Voting Rights Act Sec. 203 language minority coverage) extend the term "limited
English" to include persons who "speak English well". Under these interpretations, just one category -- "Speak English Very Well" -- defines persons
who are considered proficient in English (see Map 27).

Map 15 -- Percent Undercount

At a scale of about 5 miles, block group undercounted population (positive numbers -- persons missed) or
overcounted population (negative numbers -- persons counted twice) is displayed in purple boxes

Note: Undercount rates are calculated after removing the group quarters population. The Census Bureau did not adjust for this population because it was excluded
from the Accuracy and Coverage Evaluation.

At a scale of about 5 miles, block group counts of households without a vehicle are displayed in purple boxes.

At a scale of about 5 miles, the block group-level population 25 and over without a high school diploma is played in purple boxes.

Map 18 -- Foreign Born Non-citizen Population (any race or ethnicity, all ages)

At a scale of about 5 miles, the block group count of foreign born non-citizens is displayed in purple boxes. Percentage calculations are based on the total
population. (all ages) Note: A similar block-group level map based on single-race/ethnicity or voting age population cannot be produced due to data suppression for many block
groups.

At a scale of about 5 miles, the block group-level population for ages 15 to 24 is displayed in purple boxes.

Map 22 -- Population in Student Dorms

At a scale of about 5 miles, block group population counts for students living in college dorms are displayed in purple boxes.

This thematic map shows voting age non-English speakers who do not speak English "very well". This category includes all non-English
speakers 18 and over who speak English "well", "not well", or "not at all".

At a scale of about 5 miles , the number (by block group) of 18+ non-English speaking persons who do not speak English "very well" is displayed in
purple boxes.

Note: The language minority map is not directly comparable to Maps 11 and 12. Those maps show English proficiency by age for Spanish
speakers as a percentage of the Spanish-speaking population, rather than as a percentage of the overall voting age non-English speaking population. The maps also employ
a more restrictive definition for limited English -- "speak English not well" or "not at all". (see Map
11note)

Map 28 -- Population Under 5 Below Poverty

At a scale of about 5 miles, block group population counts for children under 5 living in poverty are displayed in purple boxes.
